Pg. 403
Organization of the Chapter:
Motivation defined
Sources of Motivation:
- Biological Factors
- Emotional Factors
- Cognitive Factors
- Social Factors
Instinct Theory:
- Automatic
- Involuntary
- Unlearned
- Evolutionary
- Aggression
- Mate Selection
Drive Reduction Theory
- Biological
- Homeostasis- tendency to keep physiological systems at a steady level or equilibrium
- Imbalance in Homeostasis creates a need- a need is a biological requirement for well-being…
- The brain creates a psychological state, called a drive…
- A drive is a feeling of arousal
- Drive reduces the need
- Drives cause organism to to take action to restore balance + reduce the drive
- The drive satisfies the need to restore balance
Optimal Arousal Theory
- Arousal-general state of activation- reflected in heart, lungs, brain, muscles
- People are motivated to behave in ways that maintain a level of arousal that is optimal, we try to increase arousal when it is too low and to decrease when it is too high
- Pg 410 Charts
- Yerkes Dodson Study- there is a curve that identifies the task to be completed and optimal arousal that matches the task.
Incentive Theory
- Behaviors that are motivated by:
- Attaining desired stimuli (positive incentives)
- Avoiding undesirable ones (negative incentive)
The value of an incentive is influenced by psychological, cognitive and social factors
Difference between wanting and liking:
Wanting is the process of being attracted to an incentive
Dopamine level controls behavior more than liking
Associated with pleasure centers in brain, like drugs
Liking is an evaluation of how pleasurable an incentive is
Hunger and Eating:
- Mix of learning, culture and biology
- Biological signals for hunger and satiety
- Blood-Glucose, Insulin, Leptin
Hunger and the Brain
- Ventro-hypothalamus = satiety
- Lateral-Hypothalamus= Hunger
- Set Point Body Weight may control appetite also
- Really neurotransmitter
Flavor-Food Selection
- Biological need for certain nutrients
- Social context
- Cultural traditions
Eating Disorders
- Obesity=over consumption
- Anorexia=starvation
- Bulimia=binge/purge
Sexual Behavior
- Motivation + Behavior due to Biology and Culture
- Biology of Sexual Response Cycle
- Sex Hormones (varied amounts)
- Androgens
- Estrogen
- Progestins
- Physical differences in brain of different sexes
- Social Cultural Factors
- Gender roles learned
- Sexual Orientation
- Hetero, Homo, Bisexual (Both nature and nurture)
- Sexual Dysfunctions
- Erectile disorder
- Premature Ejaculation
- Female arousal disorder
Achievement Motivation
- Gain Esteem from achievement
- Need for Achievement
- Motive to succeed
- Increase achievement Motives
- Strive, persist, challenge but realistic goals
- Goals Influence motivation
- Effort
- Perseverance
- Attention
- Planning
- Achievement in Workplace
- Workers satisfied when working toward own goals
- Jobs that offer
- Specific Goals
- Variety of Tasks
- Individual Responsibility
- Intrinsic Rewards are most motivating

Pg. 403 Definition of Motivation:
The factors that influence initiation, direction, intensity + persistence of behavior
Questions to be answered:
Why do we do what we do?
Behavior is based partly on the desire to feel certain emotions.
Motivation effects emotion
What are the general theories of Emotion?
How is motivation exemplified by Hunger, sexual desire and Need for Achievement?
What is the nature of emotion?
What are the main theories of emotion?
How do people communicate their emotions?
A motive:A reason or purpose that provides a single explanation for diverse behaviors.
Some psychologists think of motivation as an “intervening variable”- something that is used to explain the relationship between environmental stimuli and behavioral responses.
Sources of motivation: 4 basic categories
Biological
Emotional
Cognitive
Social Factors
4 Theories of Motivation (all use internal processes to prompt behavior)
InstinctEarly 1900s
Instincts are:
- Automatic
- Involuntary behavior patterns
- Triggered by Particular Stimuli
- Adaptive behavior
- Pre-dispositions expressed +survived and reproduced
- Genetic
- Aggression
- Helping
- Mating preferences
- Women are selective for child rearing purposes
- “Women tend to prefer athletic, symmetrical faces, deep voices; preferences are stronger at the point of menstrual cycle when fertility peaks.
- “Females generally preferred males who were mature and wealthy which shows age preferences.
Basis is Homeostasis-
- Tendency to keep physiological systems at a steady level = equilibrium
- Drive reduction says- imbalance in homeostasis creates need
- Need is a biological requirement
- Brain responds to a need and creates a drive
- Drive is a feeling of arousal that prompts an organism to action to restore balance or reduce the drive
- Example-
- Biological need for water
- Drive = thirst
- Motivates you to find water
Incentive Theory
- Emphasizes the role of external stimuli that can motivate behavior, by pulling toward or pushing us away from them.
- People behave in order to get positive incentive and avoid negative incentives
- Variables include:
- Availability of incentives
- Value someone places on the incentive
- Value is influenced by physiological, cognitive, or social factors
- “People sometimes work hard for some incentives only to find that they don’t enjoy having them nearly as much as they thought they would.”
- Wanting: the process of being attracted to incentives
- Liking: immediate evaluation of how pleasurable a stimulus is
- Different Brain Areas and Neurotransmitters
- Dopamine- associated with pleasure, sex, drugs, gambling,
- Can compel behavior in greater capacity than liking
Optimal Arousal
(Curiosity is not a drive/behavior that does not reduce a drive)
- Some behaviors increase arousal-
- Arousal= a general level of activation with physiological systems
- Example: Brain, heart, lungs and muscles
- Optimal arousal theory says we are motivated to behave in ways that maintain or restore an ideal or optimal level of arousal
- We increase arousal when too low
- We decrease arousal when to high
- Yerkes-Dodson Law
- Says we match level of arousal with a task
- Low Arousal difficult or complex
- High Arousal easy tasks
Hunger and Eating-
See Coon
Obesity:
Condition when a person’s body mass index
Weight(over) 25-29.9 = overweight
Square of a person’s height
32% of US population is obese
Diabetes, high blood pressure, heart-attack, and maybe Alzheimer’s disease
30k deaths a year and a shorter life expectancy
Psychological Explanation for Obesity
- Learned models from parents
- Evolutionary people eat more to build up for lean times (fat reserves)
- Starving does not necessarily= weight loss
- When we starve we reduce metabolism
Pg. 419 Sexual Behavior
Physiology + Learned behavior, physical + Social Environment factors
There is a diversity of Sexual Scripts= patterns of behavior that lead to sex
Researchers:
Kinsey 1940’s and 1950s used surveys to study sexual practices
Masters and Johnson 1966, in a laboratory, measured sexual arousal and behavior
Volunteers received natural and artificial stimulation problem conclusions, may not be representative of larger population (limited population sample)
University of Chicago Sex Survey:
Surveys found:
- People generally have sex = 1 per week, with a partner in stable relationship.
- Some a few times or not at all in the past year
- Average male had only 6 partners entire life
- Average female = lifetime 2 partners
- People in committed one partner relationships had the most frequent and satisfying sex
- Majority of heterosexual couples engaged in traditional intercourse
Nearly one quarter of U.S. women prefer to achieve sexual satisfaction without partners of either sex
Consistent Gender Differences:
- Men tend to have stronger interest in and desire for sex than women
- Women more likely than men to associate sexual activity with a committed relationship
Findings did not address pornography or sexual deviations, and sample was only in USA
Biology of Sex:
Master’s and Johnson identified Sexual Response Cycle:
The Pattern of physiological arousal during + after sexual arousal
Both men and women
Men / WomenResolution /
Orgasm
Plateau
Excitement
Men have 1 pattern
Resolution=relaxation
Refractory= men unresponsive
(Women don’t have this they are capable of repeating cycle)
Sex Hormones:
- Estrogens
- Progestins-Progesterone-
- Androgens = Testosterone
Each Hormone flows in blood of each Male and Female
- Average man has more androgens
- Women have more Estrogen + Progesterone
Hormone Effect on Brain:
Organizational Effects:
- Permanent changes that alter brain’s response
- Occur at birth
- Create male and female patterns
- Sexually Dimorphic (sex differences)
- Area of Hypothalamus
- Rising level of sex hormone in puberty
- Women- Estrogen + Androgens (ovaries and testes- secrete)
Activational Effects:
- Effects behavior when hormone is in blood stream
- Stimulate sexual interest (androgens and estrogens in female) (androgens only in males)
Social and Cultural Factors in Sexuality:
Learned Gender Roles- Differences
Men and porno
- MRI Study shows activity of amygdala + hypothalamus in men
Pg. 424 Sexual Orientation:
Defined: A person’s enduring, emotional, romantic, or sexual attraction to others
Hetero, Homo, Bi-sexual
- 1973 Homosexuality was dropped from the DSM Diagnostic and Statistical Manual (used for making diagnosis for abnormal behavior)
- Dropped in china as a mental disorder 2001
- Estimated 2-21 % of population is gay
What shapes sexual orientation?
- Genes may influence sexual orientation.
- Identical twin studies show, 52% correlation one gay other one is too.
- Also, twins were raised apart.
- One reason too much hormone in utero
- May also be associated with increase in androgens and altered structure
Achievement Motivation (the need to achieve)
Why do people take their work seriously and try to do the best they can?
Need Achievement:
Henry Murry (researcher)
- Found some people have need for mastery = motivation to be have competently.
- People with high need for achievement seek to master tasks & feel satisfaction
Extrinsic Motivation
- Desire for external rewards =$
Intrinsic Motivation
- A desire to attain internal satisfaction
- Desire for approval, admiration, achievement =esteem all are strong motives
People with High Need Achievement Characteristics:
- Want a challenge but not too much to prevent success
- Challenging but realistic goals
- Take risks when necessary
- Satisfied when they succeed
- If they tried their best they are not too upset by failure
- Have Self-efficacy “According toAlbert Bandura, self-efficacy is “the belief in one’s capabilities to organize and execute the courses of action required to manage prospective situations” (1995, p. 2). In other words, self-efficacy is a person’s belief in his or her ability to succeed in a particular situation. Bandura described these beliefs as determinants of how people think, behave, and feel (1994)”
- People with low N achievement success brings relief at having avoided failure
Development of Need Achievement:
- Tends to be learned in early childhood from parents
- Correlation between parent behavior + achievement motivation
- Kids with low Achievement
- Parents interfered with child difficulty
- Parents became annoyed by lack of success of kid
- Kids with High Achievement Motivation
- Parents Encourage child to try difficult tasks and new tasks
- Gave praise and reinforcement for success
- Encouraged children to find new ways to succeed
- Didn’t complain when kids experienced failure
- Prompt children to get on with the next challenge
- Children were energized by parents
- Goals increase motivation if they are realistic
- Set goals that are specific and clear
- Personally meaningful goals increase motivation
Achievement Success in the Work Place
- Low motivation
- Felling little or no control over work environment
- Create satisfaction + self-efficacy “According toAlbert Bandura, self-efficacy is “the belief in one’s capabilities to organize and execute the courses of action required to manage prospective situations” (1995, p. 2). In other words, self-efficacy is a person’s belief in his or her ability to succeed in a particular situation. Bandura described these beliefs as determinants of how people think, behave, and feel (1994)”
- Allow workers to solve problems on their own
- Individual responsibility builds motivation
- Public Recognition
- Allowing goal setting increases performance and satisfaction
Maslow and Motivation:
- Human behavior reflects hierarchy of needs and motives
- Needs at lowest level must be partially satisfied before higher level can be addressed
- “motivated by higher level goals”
- Biological- needs food – water
- Safety- secure income, family
- Belongingness and love- being part of groups, can be sexual and non-sexual
- Esteem- need to be respected as useful individual
- Self-Actualization
- Reaching one’s fullest potential
- Explore and enhance relationships with others
- Follow interests with intrinsic pleasure rather than for money, status, or esteem
- Concerned with issues affecting all people not just themselves.
Critics of Maslow:
Too simplistic
We can seek several needs at once
May not apply cross culturally
Alternate view: Alderfer
3 categories of needs
- Existence
- Relatedness- social interaction and attachments
- Growth- Developing one’s capabilities
- No particular order
- Needs rise and fall from time to time
- Situation to situation
- When a need in one area is fulfilled or frustrated, A person will be motivated to pursue some other need
Conflicting Motives:
- Motives can sometimes be in conflict
- Results in discomfort
- Motivational pushes and pulls can create internal conflict
4 types of Conflicts:
- Approach-approach Conflict:
- Choose one of the two desirable activities
- Avoidance-Avoidance
- Must choose one of 2 undesirable alternatives
- Approach Avoidance
- Single event or activity has both attractive and unattractive features
- Multiple-Approach Avoidance
- 2 or more alternatives each have both positive and negative features
- Harder to compare features
- Creates stress
- Cost-Benefit Analysis
Opponent Process Theory of Motivation
Richard Soloman
2 assumptions
- Any reaction to a stimulus is followed by an opposite reaction called an opponent process
Example: being startled by a sudden sound is followed by relaxation and relief
- After repeated exposure to the same stimulus the initial reaction weakens and the opponent process becomes quicker and stronger
Connection between motivation an emotion
Motivation can intensify emotion
Emotions can also create motivation
People want to feel happiness so they engage in behavior they think will lead to those emotions
The Nature of Emotion:
Joy, Sorrow, Anger, Fear, Love, Hate
Defining Characteristics of Emotion:
Psychological and physiological reactions
Subjective aspects
- Emotions are temporary short duration
Moods are longer lasting
- Emotions can be positive or negative or mixed
- Emotions can alter thought processes by directing attention
Negative emotions = fear can narrow emotion
Positive- can widen our thinking (think broadly)
- Emotions can trigger action tendency or the motivation to behave in certain ways
Positive emotions joy, pride lead to playfulness and creativity and exploration of the environment
Negative Emotions- sadness and fear promote withdrawal from threatening situations; anger might lead to actions that lead to revenge…
Biology of Emotion:
Involved in
Generation of Emotion
Experience of Emotion
Autonomic Nervous System
ANS is not connected to brain areas affecting consciousness
Arousal accompanies emotions
Arousal to take action
Increase blood flow and glucose to vital organs
- Sympathetic Nervous System
- Norepinephrine (Fight or Flight)
- Parasympathetic Nervous System
- Acetylcholine (slow down)
Brain mechanisms:
Limbic System
Amygdala –
- active with recognition of emotional expressions
- Damaged amygdala causes problem in recognizing emotional facial expressions
- Also perception of emotionally charged words
2 Hemispheres deal with Expressions, Experience, Perception
Right Hemisphere
Active in:
- Laughing at jokes,
- Naming emotions from facial expressions
Left hemisphere is active with making left side facial expressions
Theories of Emotion:
Questions:
Do autonomic experience create emotion?
Or, Are autonomic responses due to emotion?
How are emotional reactions affected by the way we think about events?
Main Theories are:
Biological:
- William James
- Walter Cannon
Cognitive:
- Stanley Schacter
- Richard Lazarus
James’ Peripheral Theory (also supported by Carl Lange- AKA James-Lange Theory):
Late 1800’s
You see a bear and you run- said you are afraid because you run
Perception of the bear, causes physiological response and then the fear follows.
“once you strip away all physiological responses, nothing remains of the experience. Emotion, must therefore be the result of experiencing a particular set of physiological responses.”
More Detail:
- A perception affects the cerebral cortex
- The brain interprets a situation and automatically directs a set of PERIPHERAL physiological changes
- Unconscious until we become aware of bodily changes then we experience emotion
- Implication- each particular emotion is created by a particular pattern of physiological response
- Fear from one
- Anger from another
According to James there is no emotion center to the brain, not linked to a neurotransmitter
Evaluating James Theory:
Certain emotional states are associated with certain patterns of autonomic activity (supports James)
Example- Blood Flow to hands and feet increases with anger and decreases with fear
Some autonomic activity is also associated with specific emotional facial expressions.
